If she just had crystals, she doesn’t necessarily need an Rx food. Crystals in general are not a problem, just undesired. Crystals become a problem when the pug gets a UTI. In a nutshell, the UTI promotes stone formation. If the pug has a healthy urinary tract, then UTI’s/stones should not be a problem. I would recommend visiting pugvillage.com. A community for pug lovers/owners. I’m over there too.
My pugs go see a holistic vet. They have some struvites but we feed a high protein kibble and raw food and also vinegar, d-mannose/cranberry and some vitamin c.
